Question

I want to inject a css file located on the skin folder in a browser page.

It is located on chrome://orkutmanager/skin/om.css, accessing manually show the file contents correctly.

I’ve tried this, but it’s not working… What am I missing, or is it impossible?

Answer 1

I found this workaround. Read the file then inject it’s contents…

function Read(file)
{
    var ioService=Components.classes["@mozilla.org/network/io-service;1"]
        .getService(Components.interfaces.nsIIOService);
    var scriptableStream=Components
        .classes["@mozilla.org/scriptableinputstream;1"]
        .getService(Components.interfaces.nsIScriptableInputStream);

    var channel=ioService.newChannel(file,null,null);
    var input=channel.open();
    scriptableStream.init(input);
    var str=scriptableStream.read(input.available());
    scriptableStream.close();
    input.close();
    return str;
}

var style = $("<style type='text/css' />");
style.html(Read("chrome://orkutmanager/skin/om.css"));
$("head").append(style);
